Alison Brie confirms 'Mad Men' return

However, the actress admitted that it was difficult to reprise her role as Pete Campbell's wife Trudy after appearing as Annie Edison in Community.

"To go back to Mad Men this summer after eight months of constant work on Community playing just about the opposite character was really daunting," Brie told Entertainment Weekly.

"I was very nervous I'd forgotten how to be Trudy. But then you put on the clothes and get the hair done and it is like you never left. Welcome back to the '60s. Without prodding, I'm like, 'The pot roast is ready!'"

Mad Men returns for its fourth season on Sunday, July 25 at 10pm on AMC.
